I’ve been playing this same deck when I saw it on stream but since I don’t have Thalnos swapped it with Stonehill Defender. Made it from rank 16 – 10 in about 32 games. You just gotta utilize the Death Knight (shotgun) hero power to remove board threats and when its the right time hard push for damage.

Pretty much a win against all control decks. Jade stomps on you if you don’t have the Raza and DK. Aggro is actually not as bad as Jade just depends on starting hand.

With two changes i have found this deck to have a lot of succes. If you draw both Raza and Anduin you win most games.

I have swapped Lich King for the Black Knight – he has done a lot of work for me and i do not feel like the deck needs the death knight cards.
Also i swapped Lyra for Eater of Secrets. The deck does not really have the tools to utilize Lyra, and Eater takes care of scary mage secrets, that can otherwise sabotage you quite much.

I have been toying with it and it oddly works. it has very little card draw so it needs its top-decks to be consistently strong, and I find it replies more on the big bodies to kill the opponent and uses the hero power for board control. idk how well it does against aggro, but it works against control.
